Restoration of Aquatic Ecosystems ECOR 9220

Ecological Restoration Part-time Studies Course

Course details

​​​​​​​This course will give an overview of limnology and focus on specific aspects of theoretical and applied limnology and environmental engineering required to undertake ecological restoration of lakes and reservoirs. The overview lectures discuss lake formation and basin morphometry, stratification and circulation, water chemistry (including nutrient and carbonate chemistry), BOD tests, and hypolimnetic oxygen depletion. Applied aspects of the course include experimentally determining re-aeration rates and sizing of hypolimnetic aeration/oxygenation and destratification systems, calculation of nutrient loading programs for lake and reservoir enrichment, calculation of heat budgets, and use of nutrient-loading models to assess eutrophication risk. Students will participate in lectures and group sessions and design a restoration proposal for a eutrophic winterkill lake.

Learning Outcomes

Upon successful completion of this course, the student will be able to:

  • Explain the concepts and principles of limnology relevant to ecological restoration.
  • Apply the concepts and principles in assessment and evaluation of degraded aquatic ecosystems.
  • Collect data to assess a degraded aquatic ecosystem.
  • Analyze and interpret aquatic data.
  • Integrate the concepts and principles in designing restoration activities (restoration plan) for aquatic ecosystems.

Topics include:

  • formation of lakes and basin morphometrics,
  • gas transfer theory,
  • estimating re-oxygenation parameters: KLa, SOTR, SAE and SOTE,
  • hypolimnetic oxygen depletion rates,
  • sizing and construction of hypolimnetic aeration and oxygenation systems,
  • nutrient enrichment programs for lakes, reservoirs, rivers and streams,
  • seasonal N and P co-limitation and nutrient limitation,
  • nutrient application techniques for solid and liquid fertilizer in lakes and reservoirs,
  • nutrient loading models for eutrophication risk assessment,
  • heat budgets of lakes.​
